To all whom `zit may concern:

Be it known that I, RANDOLPH C. Lorano?,

State of Massachusetts, have invented a new and useful Improvement inStreet-Car Fenders, which will, in connection with the accompanyingdrawings, be hereinafter fully described, and specifically defined inthe appended claims.

My invention relates to improvements in street car fenders and has forits object the prevention of fatal injuries to persons who maybe uponthe track and exposed to the danger of being run over and crushed by amoving car.

In the accompanying drawings, Figure l. is a perspective illustration ofmyinvention applied to the platform kot' a car. Fig. 2. is a ver- Fig.1, and as viewed from the left of said line, and showing the attachmentin its advanced position in front of the car. Fig. 3. is a like sectionshowing the attachment ref` tracted and drawn under the platform as whenfollowing the car. Fig. 4.-. is a crosssection taken as on line y y,Fig. l, and as viewed from the right of said line.

The following is a description of the method of applying my saidinvention as illustrated in the drawings, but the same may be varied indetails of construction, and must necessarily be, to some extent, topractically adapt it to the varying styles of cars to which it isapplicable. l

To the frame work A of the car platform and beneath the locringthereotare secured, manner, two horizontal side bars A and A", having thereinlongitudinal grooves B `and B. These bars, being firmly attached to the`frame work, securely uphold the sliding cross-bar C, the ends I) and Dof y which are supported by, and slide backward pose which will bestated. To bar C is attached the swivel-frame E, hung by a central boltE to bar C. The pendent sides of the swivel-frame support side bars Fand F by means of a rod G extended through said parts, so that the barsrock on the ends thereof. Bars F and F carry a shaft H upon which aresecured tivo trucks I and I', and a roll .i arn ranged to be turned inthe outer ends of the sain 110,488,051. (no man.)

y bars. Upon the inner face of truck I is secured a gear K, and uponroll .I is a smaller gear L which is arranged to be engaged and turnedby gear K to revolve the roll which is raised slightly above kthe railsL', L2, on which the car moves. Truck I is turned by frictional contactwith the rail, and through thev gears mentioned imparts a reverse motionto the roll J, so that the top of the rollturns toward the car, 'whichmotion, as before stated, tends to prevent a body from passing under theguard or fender, and to raise and cast the body up over the roll ontothe safety net J secured to the fender backl of the roll, so' as tosafely uphold and Vcarry abody cast thereon.

Said gearing may be so constructed as to increase or diminish therelative speed of the roll to such extent as may be found to be mostadvantageous in practical use. And the roll may be covered with rubber,felt, or any other suitable material to renderthe saine somewhat softand yielding, and to increase its effectiveness in adhering to, andpicking up and rolling a bodyon to the safety net or platformimmediately behind the roll. A spring M, is attachedk at one end to eachof the bars yF and F at the rear ends thereof, While the opposite endsof the springs are attached to arms N, which extend backward from thesides of frame E and constitute a part of the same. By this means thefrictional contact of trucks I and I with their rails may be increasedor diminished accordin g to the contractile force of the springsemployed. The springs also constitute an elastic connection which allowsthe trucks to yield to any inequalities in the surface of the track overwhich they roll, and to accommodate themselves to any rocking motion ofthe car occasioned by such inequalities. And the horizontal swivelmovement of frame E adapts the fender to readily follow any curves inthe track Withoutcrampiug and interfering With the easy progress of thecar around the same. The trucks and gears are covered by cases P and Pwhich keep out dirt and guard them against coming in contact with anyobject. When the fender is advanced by sliding bar C forward'in groovesB, in front of the-car, as shown in Figs. l and 2,and ready forpractical use, it may be secured in such position by stop pins R droppedthrough holes in the sides of the platform of the car and into holes IOO'Y Y yward movement ofthe car causes the trucks I and l to roll upontheir tracks, and, thus in the bar C, as shown; and may also besecuredin like manner when retracted, as shown g 1n VFlgf whenmoving atthe rearof a trav-f occupy less room cling car and so drawn in to in thestreet. Y Y Y Y The` practical operationpof my Vimproved rotary fender,above described, is probably Yipplvrent from thcdescription alreadygiven,

l Y the V:fendershould be forced into Yzo but may bebrieiiyrestated asfollows :V With tbe fender advanced Vas in Figs. l and 2, aforrolling,the gear K upon truck l being engaged yWith'the smallerV gear L, upon.roll .L

causes the roll to revolve in an opposite dig rectionV and withYincreased speed. WhenV thus in motion-if fthe Vrevolving guard-roll ofthe body of a person on the track, the effect ofi such revolving VrollVwould be to keepV the Y body from'being jammed under the fender 3,0k`for the'purposes specied: a'frevolving guard?VK the front of said frameaudl and ycrushed by the car Wheels, and with the further Vpro'baloleresult of raising;V thebody and casting it on to the net and cuing itfrom fatal injury. f
